It goes without saying here that the twin-turbo V8 petrol engine is not going to be cheap to run. It’s a case of relativity here, though. If you purchase a car priced well into six figures new, in theory you should also be able to afford to keep the thing on the road.
The 2020 model's figures still make grim reading if you're eco-minded. But then, we guess, green-minded people aren't going to be looking at a new Bentley. Fuel consumption runs to 25mpg if driven gently, and Bentley claims a range of 397 miles from a brimmed tank. CO2 emissions come in at 302g/km on WLTP testing, while the Combined fuel consumption is 21.2mpg. It's helped considerably by cylinder de-activation technology.
Of the pre-facelift models, Bentley claimed fuel economy of 19.2mpg for the W12 model. We managed slightly more still over our time with the car according to the on-board trip computer without a particular eye on saving petrol. This car also puts out 335g/km of CO2. When the W12 Speed model reappears in the UK, expect a slight improvement on these numbers.
The previously available diesel engine was a strong performer here, with a promised 35.3mpg and 210g/km of CO2, although this is no longer on sale in the UK.
It won’t come as much of a surprise that insurance and tax groups are both as high as they get, and servicing isn’t going to be cheap either, though it will be a very comfortable experience.
Reliability
- Proving reliable in service
- Technology used elsewhere, however
- Great build quality and attentive dealers
With the newly fettled, SUV-readied V8 engine and upcoming plug-in hybrid option you’d be forgiven for thinking the Bentley Bentayga’s reliability could be questionable, but the reality is it’s built using many parts from elsewhere in the Volkswagen-Audi Group (it’s based on the Audi Q7’s platform) so actually it should fare well. There haven’t been any significant recalls for the Q7 at all.
Furthermore, the build quality of the Bentayga feels exemplary. There were no indications of loose trim or rattles during our test drive.
